How do I git gud at fighting games?
Is there ranked matchmaking so I can play against similarly skilled players?
Simplest answer possible; get ready to lose a lot, but research why you lost each time and take the time to study simple tactics.
I know this might sound really stupid, but when I learned defense, I basically learned by blocking with my face. That's when I slowly learned when to block and when to not block in a fighter. That's just one example of course. You have to understand why you're being hit first. For offense that's a study of tactics that's entirely on your end; you should understand why you land the hits you do and why you don't land the hits you want on a fundamental level.
In most of them yes, but any of them that do have it don't have a player base big enough for it work.
Did anyone actually try to figure out what the tease in the picture is.
The Persona and BB color card rankings work very well for knowing someone's skill level. However these games usually have small communities online, so it's a bit of a rarity to match against exactly who you want.
Xrd's ranking system makes no sense to me though.
I got nothing on that image by the way, I have no idea. It looks like lettering drawn by fire which does not bring up anything from any fighter I've known.
